Session 12: Advances in Surface Finishing

Abstract Number:

67

Environmental compliance and safety concerns continue to ‎increase demand for trivalent chromium passivates for aluminum. ‎This presentation will provide a brief discussion on growth in the ‎aluminum market and then examine the development of a clear ‎aluminum passivates that achieves excellent corrosion protection ‎and enhanced durability. Performance factors such as passivate ‎appearance, operating range, salt spray data, post-treatment ‎applications, and benefits of trivalent Cr(III) passivation as a ‎pretreatment before lacquering, powder coating, or adhesive ‎application.‎

Passivation continues to be a robust method of extending the ‎corrosion protection of substrates. As a result of environmental ‎compliance and safety concerns, demand for trivalent chromium ‎passivates for aluminum continues to increase. This presentation ‎will provide a brief discussion on growth segments in the aluminum ‎market and then examine the development of a clear aluminum ‎passivate that achieves excellent corrosion protection and ‎enhanced durability. Performance factors such as passivate ‎appearance and operating range will be discussed, as well as salt ‎spray data, post treatment applications, and benefits of trivalent ‎passivation as a pretreatment before lacquering, powder coating, ‎or adhesive application.‎
